Usage Scenarios
This appendix provides practical usage scenarios for many of the access point’s key features. This
information should be referenced as a supplement to the information contained within this Product
Reference Guide.
The following scenarios are described:
• Configuring Automatic Updates using a DHCP or Linux BootP server
• Configuring an IPSEC tunnel and VPN FAQs
Configuring Automatic Updates using a
DHCP or Linux BootP server
This section provides specific details for configuring either a DHCP or Linux BootP Server to send
firmware or configuration file updates to an access point.
The AutoUpdate feature updates the access point firmware and/or configuration automatically
when the access point is reset or does a DHCP request. The update process is conducted over the
LAN or WAN port depending on which server responds first to the access point’s request for an
automatic update.
The firmware is automatically updated each time firmware versions are found to be different
between what is running on the access point and the firmware file that resides on the server. The
configuration file is automatically applied when the configuration filename is found to be different
between what resides on the access point and the filename residing on the server or when the
configuration version is found to be different between what resides on the access point and the
configuration version residing on the server.
The configuration version can be modified in the text file to cause the configuration to be applied
when required. The parameter name in the file is "cfg-version-1.1-01". The access point only checks
the two characters after the third hyphen (01) when making a comparison. Change the last two
characters to update the configuration. The two characters can be alpha-numeric.
